Dear all,
I have a doubt on a GML 3 OpenLayers format issue (from a WFS 1.1.0).
In GML there are two ways to list polygons points:
1. a unique posList element: the following geom is correctly transform from
GML3 to OpenLayers geometry
<gml:surfaceMember><gml:Polygon><gml:exterior><gml:LinearRing><gml:posList>-
8427711.443672495 4658480.583807316 -8428116.646618983 4671596.358484082
-8429661.427192722 4697373.995504196 -8432776.70314257 .
2. a list of pos elements: But this geom is not correctly transform
<gml:Surface
srsName="EPSG:900913"><gml:patches><gml:PolygonPatch><gml:exterior><gml:Line
arRing srsName="EPSG:900913">
<gml:pos>3944245.09999984 3978948.409156078</gml:pos>
<gml:pos>3944282.8999998407 3978974.7107042107</gml:pos> .
I think it's due to this part of code (from trunk -
OpenLayers.Format.GML.v3.js). Because on each iteration of gml pos the
points array is erased.
"pos": function(node, obj) {
var str = this.getChildValue(node).replace(
this.regExes.trimSpace, ""
);
var coords = str.split(this.regExes.splitSpace);
var point;
if(this.xy) {
point = new OpenLayers.Geometry.Point(
coords[0], coords[1], coords[2]
);
} else {
point = new OpenLayers.Geometry.Point(
coords[1], coords[0], coords[2]
);
}
obj.points = [point];
},
Does anyone know whether the GML is not conform or if it's possible to
propose a patch?
If it's not a GML conformity issue, I think that the following patch can
solve the problem but I'm not sure it's the best way:
"pos": function(node, obj) {
...
if(obj.points) {
obj.points.push(point);
} else {
obj.points = [point];
}
}
thanks,
Julien
